United States Patent O DISCHARGE OUTLET COVER PLATE Clarence J. Koranda,Western Springs, and Harry A. Withail, Chicago, 111., assignors toEnterprise Railway Equipment Company, Chicago, Ill., a corporation ofois Application February 2, 19575, Serial No. 485,789 Claims. (Cl.10S-282) This invention relates, generally, to discharge outlets forhoppers for railway cars, trucks and the like and it has particularrelation to the attachment thereto of a sanitary plate used to preventcontamination of the interior of the discharge valve housing of thehopper and the underside of the movable gate which controls the flow oflading therethrough.

Among the objects of this invention are: To provide simple, eicient andeconomical means for holding a removable sanitary plate in place on theunderside of a discharge valve of a lading containing hopper; to holdthe plate in place by wedging action; to employ a locking bar wedginglysupported at its ends for underlying the plate and holding it in closedposition; to support the locking bar by a stationary keeper at one endand a pivoted keeper at the other; to provide cooperating engagingwedging surfaces on the keepers and the respective ends of the lockingbar; to hold the locking bar in place by a removable locking pin; and toprovide for applying 'torque to the pivoted keeper for swinging ittoward the 'stationary keeper and wedging the plate into closedposition.

Other objects of this invention will, in part, be obvious I and in partappear hereinafter.

This invention is disclosed in the embodiment thereof shown in theaccompanying drawing and it comprises the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth and the scope ofthe application of which will be indicated in the appended claims.

For a more complete understanding of the nature and scope of thisinvention reference can be had to the following detailed description,taken together with the 4accompanying drawing in which:

Figure 1 is horizontal sectional view taken generally along the line 1 1of Figure 2 and showing the housing lgenerally along the line 3 3 ofFigure l; and

Figure 4 is a fragmentary view in end elevation of the construction asshown in Figure 1, the view being taken from the left hand end of thisgure and looking from left to right.

Referring to the drawing, it will be observed that the referencecharacter 10 designates a rectangular steel or cast iron housing whichis located around a discharge opening 11 of a discharge valve for a loadcontaining hopper. It will be understood that the housing 10 dischargesdownwardly and -that the discharge of the lading from the hopper iscontrolled by a slidable gate (not shown) or other suitable valve meanswell known in the art. The present invention has to do with theprotection of the underside of such a gate and the interior of 'thehousing 10 from contamination. This is important when the hop- V2,751,858 ce Patented June 26, 1956 2 per with which the housing 10 isassociated is employed for transporting our, sugar or the like.

Extending outwardly from the lower edge of the housing 1G is a angehaving portions 12 and 13 at the ends and 14 and 15 at the sides asshown more clearly in Figure l. Against the undersides of these flangeportions there is positioned a removable sanitary plate 16. interposedbetween the upper surface of plate 16 and the under surfaces of theflange portions is a gasket 17. lt will be observed that the angeportions 13 and 15 are provided with inwardly opening slots 19 and 21for receiving the corresponding edges of the sanitary plate 16 and alsofor receiving a detachable connection to a conveying conduit which isapplied to the housing 10 in lieu of the plate 16 for unloadingpurposes.

The underside of the sanitary plate 16 is provided with transverse ribs22 each having a central slot 23 for receiving a locking bar 24 that mayhave a square cross-section as shown more clearly in Figure 3. The upperside of the locking bar 24 bears against the underside of alongitudinally extending rib 25 that is formed integrally with theunderside of the plate 16. Provision is made for wedgingly holding theplate 16 in the closed position through the agency of the locking har24. The details of this construction will now beset forth.

In Figure 2 it will be noted that the underside 2S of the right hand endof the locking bar 24 is inclined upwardly so as to wedgingly engage anupwardly facing downwardly and inwardly inclined wall 29 of a stationarykeeper 30 that is carried by the housing 10. Preferably the stationarykeeper 30 is cast integrally with the housing 10, although it may besecured thereto by other means as desired.

A somewhat similar construction is provided at the left hand end of thelocking bar 24. Its underside 32 is inclined upwardly in order towedgingly engage an upwardly facing downwardly and inwardly inclinedwall 33 of a pivoted keeper 34. The keeper 34 has an upwardly extendingarm 3S which is positioned between spaced ears 36 that project upwardlyfrom the ange portion 12, Figure 4. A rivet 37 extends through the ears36 and the arm 35 for pivotally mounting the keeper 34 so that it canswing toward and away from the stationary keeper 30.

With a view to employing the wedging action that is provided through theagency of the interengaging undersides 28 and 32 of the locking bar 24with the walls 29 and 33, a socket 38 is formed in the keeper 34 forreceiving a removable bar that is indicated by conventional broken linesat 39. When the bar 39 is inserted in the socket 38 and is moveddownwardly, the resultant torque applied to the keeper 34 swings ittoward the stationary vkeeper 30 and moves the locking bar 24 upwardlyto force the sanitary plate 16 into sealing engagement with the gasket17.

In order to hold the locking bar 24 in operative position ears 41 areformed integrally with the keeper 34 and they extend inwardly therefromon opposite sides of the left hand end of the locking bar 24. The ears41 are provided with elongated apertures 42 which are arranged toregister with a circular aperture 43 in the left hand end of the lockingbar 24. A locking pin 44 extends transversely through the apertures 42and 43, as shown in Figure 4, to lock the assembly in the position shownin Figure 2. A sealing strip 45 extends through one end of the pin 44 toprevent unauthorized withdrawal. A chain 46 is secured to the other endof the locking pin 44 and to a staple 47 projecting upwardly from theange portion 12 to prevent loss of the locking pin 44 when it iswithdrawn from operative position.

In operation, when it is desired to remove the plate 16, the sealingband 45 is removed and the locking pin 44 is vvritldravv'n.Vlpe'r'n'iits the pivotedkeeper 3d to swing Y The housing 116' is closedott 4byfapplying the plate 16V after the' ladinghas been discharged;Then the bar 24 is inserted inthe f keeper 30 and thejkeeper 34 is swungto engage the other end'. The bar Q9 is inserted` in the socket 38 andthe keeper 34 is movedtowardthe keeper 3 9 until the 'apertres'Z in' the`ears`41 register with the aperture $3 'in 'the left hand end 'of thebar24. The locking pin 44 then is inserted and thesealing band 451applied.

Sincefcertain' changes can be made in the' foregoing construction anddiierent embodinflents of the invention can be made withoutA departingfromjthespirit and scope thereof, it is intended that all matter shownin the 'accompanying drawing and described hereinbeforeshall beinterpreted as illustrative and not in a limiting sense.
